Samsung Galaxy S2 Battery Life not good

[Homeuser66]

Hi, this issue is specific to my NON-ROOTED Samsung Galaxy S2. I have seen other simsilar issues for other phones and they don't seem to help. My Battery doesn't seem to last more than a few hours. No more than 5-8 and it's dead. I turned off the Data and wi-fi. I set my Wallpaper to a Black background. It just sits on the desk and after a few hours it's almost dead...

What can I do to fix this?

Rooting is not an option at the moment.. I'm still reading and learning about it as I don't want to create a paperweight and/or void my warranty...

No offence mate but for a start you can search the forum and you will literally find dozens of threads on the very same subject which have been posted on here over the last few months.

Search and you'll find the answers your looking for, a tip freeze the Samsung bloatware in Titanium Backup and your battery life will improve substantially, there are many other methods to improve battery life you can find them yourself.

I get over a full day on heavy usage...

No offense taken, but most point to Rooting my phone...This is not an option for me at this time....I'll look some more, I guess...

Oh right well then your options are limited if your not going to root your phone as regards battery life.

I know...that's why I posted, but I should have said that in my original post...I'll edit it....but I did find something that I will try when I can..Phone is charging in a wall outlet right now, and I don't want to unplug it. lol...I do thank you for your effort and understanding...

I have unrooted phone and get around 17-20 hours heavy usage.

I would suggest you flash a 2.3.5 Rom via Odin as they seem to have better battery management if you haven't done so

you dont need to be rooted to flash new roms via odin

Also advisable to charge battery till full then use till its like 1% then recharge full and so on to calibrate it a bit.

Rogue apps can eat your battery life as well so If you can afford it do a full wipe and reset if you can and see if it makes a difference.

If her wifi is on and its constanly looking for wifi, will that be the cause? i just told her to turn that off.

Chat applications like Google Talk or Facebook (if you go into Chat) tend to drain battery.

You guys need to give more information if you really want decent assistance, there is an app called better battery stats, you want to look at your partial wakelocks section in that particular app, go get it either on this forum or in the Market, post screenshots of your battery graph in Settings>About Phone>Battery Usage and click on the time, also a screenshot of your partial wakelocks will reveal the issue 90% of the time

Also, there is no need to root your phone to achieve good battery life, unless it is found that a system app may be the cause of the poor battery which is hardly ever the case, anyone who points you to rooting to get good battery life has very limited knowledge of android and what is the cause of poor battery life...

Usually downloaded apps and user settings are the cause of poor battery, there is absolutely no need to root to be able to fix those problems.....

 

[UnwiredDroid]

I noticed this one too...My stock DXI2 room tend to be a battery hogger and the display consumes around 60% of my entire battery life...

 

[jr866gooner]

agreed I'm getting nigh on 2 days battery life nowadays maybe one and a half of moderate to high usage! certainly don't need to root and install a new ROM.

Ok, so I am attaching my screen shots for you to look at..There are 2 of them, as I can't figure out how to take a scrolling screen shot, which I don't think there is a way...but I'm still in the learning process...lol

These were taken at 2am EST after a full battery charge...It says 22 hrs on the top...I'll be lucky if I get 6...

The time is now, 10:15 am EST. I have turned off GPS. Force Stopped Solitare (Wife likes to play that)and it says: 4h 52m 35s on battery..not sure how to read this? Is this how long it's been on? or that I have battery left?

Display 49%
Cell standby 15
Phone idle 10
Android 8
Clock 5
Android system 4
Messaging 2
Calendar 2
The reset 2

 

[jr866gooner]

Charge your phone fully and use it as you would normally, the screenshots you provided doesn't show much, what you have to do is click on the very top where it says 22h 52m, that would take you to another shot that shows your "screen on" time in a linear graph just below "Awake" time, that's the screen that would tell us if you are having wakelocks.

Secondly, get better battery stats from the market or from this link here then set the display options to "Partial Wakelocks" "since unplugged", remember you do this after using your phone normally from 100% to 50%, this should be able to give us some insight into what is eating your battery, it may be better to let the phone sleep as much as possible, but I know it's pretty hard to leave the device alone......

You should definitely try better battery stats app. It helped me to identify the app that kept my phone awake continuosly. My battery life increased from 8-9 hrs to 15-17 hrs after uninstalling that app. I even bought the paid version from market after that. Must have app!!! Give it a shot. Its free for XDA users. But if it helps you then please do consider buying it to support the developer.

 

[devvfata1ity]

yup. My SGSII is on KJ3 stock & I get easily around 1 day & 16-17 hrs before i need a charge. This is with moderate to heavy usage (depends on your perspective) which includes:

1. Display is on roughly 1.5 to 2 hrs
2. Voice calls roughly 2-3 hrs
3. 100 odd texts
4. 30-40 mins of listening to music
5. 20-30 mins of browsing
6. 30 mins of running benchmarks
7. 10-15 mins of gaming
8. Downloads for 30 mins
8. Auto-sync & background data enabled for 9-10 hrs

Ok, I had the phone plugged in to the laptop to transfer my Memo's from my BB/Outlook over to the phone, so it only says it has been unplugged for 3 min..If you want longer, let me know, as I'll do another one tomorrow.

This one is from 49 min unplugged...

As far as that app. I'll download it now and run it for a day or two and see what happens...will post back soon!
Thanks for all your help people!!!

My non rooted galaxy s ii lasts at least on full day of heavy usage, including 3g, music, and gps. Will last 2 to 3 days if i use it conservatively turning off 3g when not in use.

make sure u have latest update thats basically all i did.

good luck.
